Patent GB-328872-A (GB)
IPC: A47J39/00
Filed: 1929-07-20
Abstract: 328,872. Soc. L'Auxiliaire des Chemins de Fer et de l'Industrie. April 12, 1929, [Convention date]. Addition to 313,481. Feedwater, heating.-In a direct contact steam feedwater heater the excess of hot water obtained is discharged, by an automatic valve, directly into the inflow of the cold water pump or into one end of the pump cylinder instead of into a receptacle connected to the pump inflow, as in the parent Specification. The cold water pump 24 discharges water into chamber 20 through the spring 23 where it is heated by direct contact with steam and then passes out in chamber 21. Excess hot water accumulates in tube 2 until its hydrostatic pressure raises valve 5 and the water escapes through orifice 73 into vessel 70 from which pump 24 sucks. Pipe 3a connects the top of cylinder 4 to the steam space of chamber 21, thus causing a constant control pressure on valve 5, while a small orifice 63 allows any condensate above valve 5 which would interfere with working to escape without serious loss of steam. If water works up the side of valve 5 when the pressure in chamber 21 is low it enters the annular recess 77 and escapes through the outlet 79. The excess hot water may also pass directlv into the end 89 of the pump cylinder through a passage 80 provided with a non-return valve 82. In that case cold water alone is supplied to the end 88 so that even if the end 89 fails owing to the high temperature of the water from chamber 4 chamber 20 is still supplied. Specifications 313,481 and 314,368 are referred to.

Title: Fuel control apparatus for a gas turbine engine
IPC: F02C9/26
Filed: 1971-04-19
Abstract: 1298907 Gas turbine engine fuel systems UNITED AIRCRAFT CORP 19 April 1971 [20 March 1970] 22598/71 Heading F1G [Also in Division G3] An isochronous governing system for a turbine as described in Specification 1297601 includes a valve 116 which is actuated by the difference between the scheduled and actual operating conditions of the turbine so that the governing signal is interrupted should the acceleration of the turbine be over the prescribed limit. The position of the fuel metering valve, which is indicative of the square root of the fuel flow, is fed to an arm 190 where a dividing mechanism actuated in accordance with compressor discharge pressure creates a signal which is proportional to the square root of the fuel flow divided by the square root of the compressor discharge pressure. This is compared with a signal of the scheduled condition, which is a function of compressor inlet temperature and compressor speed, from a three dimensional cam 164 by a linkage 160. During steady state condition flow through the valve 116 is undisturbed. The chamber 72 of the fuel metering valve is therefore placed in communication with the governor signal via line 114, the high pressure port 222 or drain pressure port 214 of the valve 116 according to the output of the linkage 160. Alternatively the valve 116 may be placed in parallel with the governor signal Fig.4 (not  shown) in which case a selector valve (330) is additionally provided to select the lower pressure signal from the governor and "acceleration" signals and the greater pressure signal from the governor and "deceleration" signals to actuate the fuel metering valve.

Title: Improvements in or relating to paper feeding machines
IPC: B65H9/14
Filed: 1929-07-23
Abstract: 327,651. Brehmer Maschinen-Fabrik, Geb., and Kleinschmidt, O. July 23, 1929. Sheet-registering devices.-In sheet-feeding devices for folding or like machines of the kind in which the sheets are forwarded by rising and falling rollers c and conveying bands b to sheetregistering stops l, damage to the sheets by the stops l is prevented by reversing or suspending the action of feed rollers g, which co-operate with the bands b to advance the sheets at the moment the, sheet reaches the registering stops. The rollers g are preferably mounted on bars f, which are used to prevent lifting of the sheets, and are each connected by a light pitman h to a lever i fitted with a counterweight k. As the sheets move forward the lever i is moved bodily in the same direction. When a sheet reaches the stops l, the continued rotation of the rollers g cause them to move bodily in a reverse direction to the position shown in Fig. 4, and no pushing action is exerted on the sheet. The rollers g are preferably mounted in ball bearings, and the rollers may be replaced by balls freely movable in straight guides, or by any equivalent construction, such as drag springs suspended from levers and adapted to be carried along by the sheet, and to perform a return movement under the influence of a counterweight.

Title: Improvements in Cathode Ray Tube Focusing Arrangements
Inventor: KIRKHAM RAYMOND
IPC: H04N3/26
Filed: 1967-05-17
Abstract: 1,187,303. Cathode-ray tube circuits. RANK ORGANISATION Ltd. 8 May, 1968 [17 May, 1967], No. 22855/67. Heading H4T. [Also in Division G4] The beam of a cathode-ray tube is maintained in sharp focus at all deflected positions by applying to the focusing means a signal, representative of the instantaneous beam position, derived from non-linear amplifying means to the input of which full-wave rectified beam deflection signals are supplied. Such signal may be derived from scanning circuits (e.g. the line and frame generators in the case of television receiving or transmitting apparatus) or, where the beam is deflected additionally to scanning (e.g. in an oscilloscope for waveform display), from the means producing such deflection. The described embodiment is concerned with a flat-faced electromagnetically focused cathoderay tube the beam of which is scanned in two mutually perpendicular directions X, Y. To maintain the beam in sharp focus independently of its position with such a tube the focusing current must be (approximately) proportional to K 1 X<SP>2</SP> + K 2 Y<SP>2</SP>, where X and Y are the instantaneous displacements of the beam from the centre of the screen and K 1  and K 2  are constants. To produce the K 1 X<SP>2</SP> component the deflection signal for the line scan is fed via a series resistor (not shown) to the input terminals 2 and reduced to its modulus by full-wave rectification by means of transistor TR 2 , TR 4 . The output from the latter is then fed to a non- linear amplifier comprising transistors TR 6 , TR 8 , TR 10 , TR 12  the characteristic of which effects squaring of the input signal and the squared output is then utilized via transistor TR 14  to control the current flowing through the focusing coil 10. A similar circuit feeding a separate focusing coil may be employed for the K 2 Y<SP>2</SP> component or the outputs of the two circuits may be combined and fed to a single focusing coil. In the case of an oscilloscope-type display in which the beam is scanned in one direction and deflected in the other direction by the waveform to be displayed the components are produced under the control of the scanning waveform and the actual deflection waveform to be displayed. The invention is also applicable to systems in which the beam is simultaneously scanned both radially and circumferentially and to tubes utilizing electrostatic focusing instead of electromagnetic focusing.

Filed: 1971-04-19
Abstract: 1333641 Selective printing HONEWELL BULL (NEDERLAND) NV 19 April 1971 [4 Marcn 1970] 22871/71 Heading B6F [Also in Division H2] A device for converting rotational motion into linear motion, particularly for traversing the striking mechanism of a series printer, comprises co-operating male and female threaded elements, the thread on the male element being of smaller external diameter than the internal diameter of the thread on the female element and one of the elements being rotatable whilst the other is prevented from turning, one of the elements also carrying a coil for generating magnetic flux which closes through both elements. In Fig. 1, the female element is in the form of a nut 2 slidable on a threaded rod 1 which can be driven through gearing 5, 6. The nut carries a coil 10 and is held against rotation by a shaft 12. On energization of the coil the threads of the nut and rod align and rotation of the rod in the direction of arrow f causes the nut to traverse in the direction F 1 , at the same time compressing a spring 14. On de-energization of coil 10, the spring 14 slides the nut rapidly along the rod in the opposite direction. Alternatively the nut may be fixed and the rod movable longitudinally against a spring, one of the gear wheels (10) being elongated to provide a continuous drive, Fig. 2 (not shown). Fig. 3 shows another embodiment wherein a longitudinally movable male element 20 carries the coil 10 and co-operates with an elongated rotatable female element 23. The male element may be stationary and the female element movable longitudinally, Fig. 4 (not shown). In the further embodiment shown in Fig. 7, a female element 45 in the form of a nut cooperates with a pair of threaded rods 42, 43 driven in opposite directions by gearing 39-41. The element 45 carries a pair of coils 47, 48 surrounding rods 42, 43 respectively so that it can be caused to traverse in either direction by energizing the appropriate coil through a change-over switch 50. The gearing can be arranged so that one rod is driven faster than the other to give a geater speed of traverse in one direction.

Title: Improvements in or relating to continuous fractional distillation
Inventor: HUNNIKIN CYRIL
IPC: C07C37/74
Filed: 1949-09-05
Abstract: <PICT:0702823/III/1> In a continuous fractional distillation process carried out under reduced pressure, particularly for the dehydration of crude tar acids, the feed is preheated and partially vaporized by indirect heating with low grade steam at 3 to 15 pounds per square inch (gauge), and the vapours from this preheating stage are passed to a rectification stage, while the liquors from the preheating stage are passed to a stripping stage.  The liquid withdrawn from the stripping stage is submitted to rectification, and the vapours so obtained may be condensed in water-cooled "evaporative condensers", the steam from which is used for the preheating stage.  Liquor consisting of tar acids containing water, is pumped through pipe 2 into preheater 3 which contains a heating-coil 4 supplied, through pipe 5, with steam at a pressure of 3 to 10 p.s.i.g., from evaporative condensers 28 and 35.  Preheater 3 is disposed between the rectification-section 7 and the stripping-section 11 of a distillation column, which is maintained under reduced pressure by pump 43.  Some of the water in the feed is vaporized in preheater 3. The vapours liberated in preheater 3 enter rectifier 7, while the residual liquor overflows through pipe 10 into stripper 11.  The remainder of the water is vaporized in stripper 11, the vapours from which are passed, through pipe 12 into the rectifier.  Dehydrated tar acids collect in reboiler 13 which is heated by live-steam heater 14. The vapours (steam and some tar acids) which leave the head of the column, are condensed in condenser 8; and the condensate is withdrawn through pipe 9. The dehydrated tar acids are transferred from reboiler 13 into column 25, which is also maintained under reduced pressure by pump 43.  The base of column 25 is connected to a heat-exchanger 26 supplied with steam at 150 to 250 lbs. pressure. Phenol and cresols vapours leave the head of column 25, and are condensed in water-cooled evaporative condenser 28; and that part of the condensate which is not returned to the column as reflux, is withdrawn from the system as product via barometric seal 30.  The liquor collecting in heat-exchanger 26 is transfered via pipe 31 to evaporator 32, where the xylenols fraction is vaporized.  The xylenols are condensed in water-cooled evaporative condenser 35, which is maintained under reduced pressure by pump 46.  Pitch is withdrawn from the base of the evaporator.  Specification 608,038 is referred to.
